Description

Technical Field

[0001] This utility model relates to the field of automatic assembly equipment, and in particular to an automatic bonding and assembly device. Background Technology

[0002] During the product manufacturing process, cushioning and protective materials, such as foam, need to be precisely attached to designated locations inside the gift box. Currently, the industry generally adopts a traditional manual production model for attaching foam inside gift boxes. This requires multiple manual intervention steps, which is cumbersome and difficult to achieve continuous production. Under the traditional manual attachment model, operators need to complete a series of tedious processes such as picking up and placing cushioning materials, positioning the materials to be attached, applying glue, attaching, and de-bubbling. This is not only labor-intensive, but also requires multiple operators on a single production line. Production efficiency is limited by the operators' skill level and physical strength. During the manual attachment process, factors such as the operator's operating technique, force, and attention can all affect the attachment quality, easily leading to problems such as misalignment of cushioning materials, uneven glue application, and air bubbles in the attachment gaps, resulting in a high product defect rate.

[0003] For incoming bulk cushioning materials, such as EV foam, the material is usually adhesive-backed. The adhesive must first be removed from each individual piece of foam manually before die-cutting into smaller units. These units are then manually placed in reverse onto a specialized fixture. Product boxes are then picked up one by one from the production line, aligned with the foam on the fixture with the box opening facing down, and then manually returned to the production line. This entire process relies on manual separation by operators, requiring high precision in placement. Uneven force can easily lead to deformation of the cushioning material, damage to the adhesive, and unevenness between the cushioning material and the substrate, causing air bubbles. Furthermore, the extraction of individual materials requires significant time, necessitating repeated adjustments to ensure subsequent bonding accuracy, further increasing processing time. Manual operation is also susceptible to operator fatigue and skill levels, making it difficult to guarantee consistent bonding accuracy and potentially leading to wasted cushioning material or damaged product boxes due to operational errors, further increasing production costs and quality risks.

[0004] Therefore, a new technical solution is needed to address the problems existing in the current technology. Utility Model Content

[0010] Preferably, the lower end of the pickup component is detachably connected to a suction cup.

[0011] Preferably, the defoaming station is equipped with a defoaming component and a buffer material detection device.

Preferably, the defoaming assembly includes a defoaming drive and a defoaming plate fixedly connected to the output shaft of the defoaming drive.

[0012] Preferably, the lower end of the defoaming plate is fixedly connected with a number of defoaming components equal to the number of dispensing positions.

[0021] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 , Figure 2 and Figure 5As shown, the automatic bonding and assembly device includes a feeding component 1, a bonding and assembly component 2, and an adhesive supply system 3. These components work collaboratively to achieve a fully automated process for cushioning material bonding, from feeding, inspection, dispensing, bonding to debubbling. This significantly improves production efficiency, reduces labor costs, and ensures consistent product bonding quality through precise control at multiple stages, meeting the needs of large-scale production. In at least one embodiment, the automatic bonding and assembly device is installed inside an aluminum profile frame. The aluminum profile frame has excellent load-bearing capacity and structural stability, effectively supporting the long-term stable operation of each component. Except for one side of the feeding component 1, the frame is fitted with acrylic glass, facilitating material replenishment by operators. This design fully considers production safety and operational convenience. The acrylic glass clearly displays the operating status of each station inside the device, allowing operators to monitor the production process in real time, promptly detect and handle abnormalities, and effectively isolate the internal mechanical moving parts, preventing foreign objects from entering or accidental contact by operators during production, thus avoiding safety incidents. Therefore, an operating device with a human-machine interface is installed on the side wall of the frame near the material feeding area. Operators can use the operating device to start and stop the equipment, set parameters, and query production data. This allows for precise control of the entire automatic bonding and assembly device, ensuring that all links work in a coordinated and orderly manner. It balances safety and ease of operation, and guarantees production stability from an overall architecture perspective. Compared with the traditional manual bonding mode, this automatic bonding and assembly device significantly improves production efficiency and reduces labor costs. Through precise control of multiple links, it strictly controls the product bonding defect rate and ensures that the product has stable bonding quality.

[0022] like Figures 2-4As shown, the feeding assembly 1 includes a frequency controller 11, several vibrating trays 12, and a positioning station 13. The frequency controller 11 controls the vibration of the vibrating trays 12 to transport the cushioning material in the vibrating trays 12 to the positioning station 13. By precisely adjusting the vibration frequency of the vibrating trays 12 through the frequency controller 11, cushioning materials of different specifications can be stably transported. The vibrating trays 12 include a first feeding tray 121 and a second feeding tray 122. The discharge end of the first feeding tray 121 is connected to the positioning station 13. The discharge direction of the second feeding tray 122 is perpendicular to the discharge direction of the first feeding tray 121. By increasing the number of vibrating trays 12 through reasonable layout, the feeding assembly 1 can simultaneously provide the cushioning material required by multiple dispensing positions 233. Since the discharge end of the second feeding tray 122 is horizontal, the cushioning material cannot directly reach the positioning station 13. Therefore, the discharge end of the second feeding tray 122 is connected to the positioning station 13. A pusher track 14 is provided between the three sections. The length direction of the pusher track 14 is the same as the discharge direction of the first feeding tray 121. A pusher device 141 is installed on the pusher track 14, which can slide back and forth between the discharge end of the second feeding tray 122 and the positioning station 13. The pusher device 141 pushes the cushioning material conveyed by the second feeding tray 122 to the positioning station 13 along the pusher track 14. The pusher device 141 includes a pusher 1411 and a separator 1412. The length of the separator 1412 is greater than the distance between the discharge end of the second feeding tray 122 and the positioning station 13. When the pusher 1411 pushes the cushioning material, the separator 1412 blocks the subsequent feeding of cushioning material in the discharge end of the second feeding tray 122, so as to prevent excess cushioning material from entering the pusher track 14 or leaving the discharge end of the feeding tray, causing waste of cushioning material and affecting the bonding of the material to be bonded and the cushioning material.

[0023] In at least one embodiment, the feeding assembly 1 includes three vibrating feeders 12, two of which are first feeding feeders 121 and one is a second feeding feeder 122. The discharge direction of the first feeding feeder 121 is longitudinal, and the discharge direction of the second feeding feeder 122 is transverse. The second feeding feeder 122 is installed on the side of the first feeding feeder 121 near the defoaming assembly 4. The length direction of the push track 14 is perpendicular to the discharge direction of the second feeding feeder 122. The pusher 1411 is driven by a linear module to slide back and forth between the discharge end of the second feeding feeder 122 and the positioning station 13 along the push track 14. The pusher 1411 and the separator 1412 are integrally formed. The cross-sectional shape of the pusher 1411 is Z-shaped, and the separator 1412 is a long strip plate.

[0024] In actual operation, the operator can send a frequency adjustment command to the frequency controller 11 through the human-machine interface according to the specifications of the cushioning material, such as size, weight, and material. After receiving the command, the controller will adjust the output current frequency in real time, thereby changing the vibration intensity of the vibrating material tray 12. For cushioning materials that are small in size and light in weight, the vibration frequency needs to be reduced to avoid damage to the cushioning material or disordered conveying due to excessive vibration intensity. For cushioning materials that are large in size and heavy in weight, the vibration frequency needs to be increased to ensure that the cushioning material can be conveyed forward smoothly. When the vibrating material tray 12 vibrates under the control of the frequency controller 11, the cushioning material will be conveyed to the positioning station 13 under the action of inertial force and friction. The cushioning material pick-up fixture 5 accurately picks up the cushioning material in the positioning station 13 and transfers it to the bonding station 24, realizing the precise positioning and transfer of the cushioning material, reducing manual intervention. The feeding component 1 realizes the automated and precise conveying of the cushioning material, improves the feeding efficiency and accuracy, and reduces the damage rate of the cushioning material.

[0025] like Figure 5 As shown, the bonding assembly component 2 includes a flow channel 21 and a material detection station 22, a dispensing station 23, a bonding station 24, and a defoaming station 25 arranged sequentially along the flow channel 21 in the direction of conveying the material to be bonded. The glue supply system 3 supplies glue to the dispensing station 23. The material to be bonded is conveyed to the dispensing station 23 for dispensing. The feeding component 1 conveys the buffer material to the bonding station 24. The buffer material and the dispensed material to be bonded are bonded at the bonding station 24. Limit bars 26 are provided on both sides of the flow channel 21. The limit bars 26 restrict the material to be bonded to be kept in the flow channel 21 and are smoothly conveyed to each station through the flow channel 21.

[0026] like Figure 2 and Figure 7 As shown, a buffer material picking fixture 5 is provided between the positioning station 13 and the bonding station 24. The material to be bonded is provided with adhesive dots 233. The positioning station 13 has a number of positioning grooves 131. The height difference between the inner bottom walls of any two positioning grooves 131 is the same as the height difference between the upper surfaces of the corresponding two adhesive dots 233. The buffer material picking fixture 5 includes picking parts 51 corresponding to the number of positioning grooves 131. The length of any two sets of picking parts 51 is the same as the sum of the heights of the adhesive dots 233 of the corresponding material to be bonded. Since the required heights of the adhesive dots 233 are different, the structure of the positioning grooves 131 has been improved, which helps to facilitate the process of picking up the buffer material and bonding it to the material to be bonded.

[0027] In at least one embodiment, three dispensing positions 233 are provided in the material to be bonded, the positioning station 13 has three positioning grooves 131, and the buffer material picking fixture 5 includes three picking parts 51. The lower end of the picking part 51 is equipped with a suction cup. The suction force of the suction cup picks up the buffer material and moves the buffer material to the dispensing position 233. The height of the inner bottom wall of the positioning groove 131 connected to the second loading tray 122 is higher than the other two positioning grooves 131. The dispensing position 233 corresponding to the positioning groove 131 connected to the second loading tray 122 is higher than the other two dispensing positions 233. The picking part 51 corresponding to the positioning groove 131 connected to the second loading tray 122 is shorter than the other picking parts 51.

[0028] like Figure 5 and Figure 8 As shown, the material orientation detection station 22 is equipped with a camera component 221 for detecting and confirming the orientation of the material to be bonded. The camera component 221 can flexibly adapt to the orientation detection of materials of different sizes, quickly confirm whether the placement of the material is correct, avoid subsequent bonding deviations due to incorrect material orientation, and ensure bonding accuracy.

[0029] like Figure 2 and Figure 7 As shown, the dispensing station 23 is equipped with a dispensing device 231, which dispenses adhesive at specific points onto the material to be bonded. The dispensing station 23 is also equipped with an adhesive detection device 232, which is installed on the worktable between the dispensing station 23 and the bonding station 24. The dispensing device 231 dispenses adhesive at specific points onto the material to be bonded, ensuring accurate adhesive dosage and placement. The adhesive detection device 232 monitors the amount and position of adhesive in real time, and can clearly capture adhesive traces on the material to be bonded, promptly identifying and troubleshooting issues such as insufficient or missing adhesive, ensuring stable dispensing quality, and providing reliable bonding assurance for the subsequent bonding of buffer materials and the material to be bonded. The capacity of the adhesive storage tank in the adhesive supply system 3 can meet the dispensing needs for a long time. The delivery pump is a gear pump with stable delivery pressure, ensuring that the adhesive can be delivered evenly and continuously to the hot glue gun.

[0030] like Figure 2 and Figure 5As shown, the bonding station 24 receives the buffer material and the dispensing material to be bonded from the feeding component 1 to the positioning station 13, enabling precise bonding and reducing product defects caused by misalignment. A buffer material pick-up fixture 5 is installed between the positioning station 13 and the bonding station 24 to transfer the buffer material from the positioning station 13 to the bonding station 24. The buffer material pick-up fixture 5 adopts a vacuum adsorption structure, and the adsorption surface of the pick-up fixture 5 is the same shape as the buffer material, ensuring a tight fit to the surface of the buffer material and improving the stability of adsorption. The suction cup is a vacuum suction cup made of wear-resistant silicone material, which has good sealing and elasticity and can effectively protect the surface of the buffer material from damage. The suction system of the buffer material pick-up fixture 5 includes a vacuum pump, which can generate sufficient adsorption force to ensure that the buffer material will not fall off during the transfer process.

[0031] like Figure 5 and Figure 6 As shown, the defoaming station 25 is equipped with a defoaming component 4 and a cushioning material detection device 44. This eliminates air bubbles generated between the cushioning material and the material to be bonded, improving the bonding strength and ensuring the flatness of the final product appearance. After the cushioning material detection device 44 detects the cushioning material on the dispensing position 233, the defoaming component 4 presses down on the bonding area between the cushioning material and the material to be bonded to remove bubbles. The defoaming component 4 includes a defoaming drive 41 and a defoaming plate 42 connected to the output shaft of the defoaming drive 41. The defoaming plate 42 can withstand the stress generated by long-term pressing operations, preventing deformation. The lower end of the defoaming plate 42 is equipped with defoaming components 43, the same number as the dispensing positions 233. The lower end face of the defoaming component 43 has a groove. The difference in depth between any two grooves is the same as the difference in height of the upper end face of the corresponding dispensing position 233. The defoaming component 43 ensures complete coverage of the bonding area of ​​the material being bonded. To ensure that the buffer material remains within the pressure groove during defoaming and prevent displacement, the defoaming plate 42 is equipped with a buffer material detection mounting position 421. A buffer material detection device 44 is mounted on this position, ensuring precise and secure installation. This allows for synchronized movement with the defoaming plate 42, improving the response speed and ensuring accuracy and timeliness. After the buffer material detection device 44 accurately identifies the buffer material within the defoaming space, the defoaming drive component 41 drives the defoaming plate 42 to vertically press down on the bonding area between the buffer material and the material to be bonded, efficiently removing air bubbles from the bonding gap. This ensures a tight bond between the buffer material and the material, improving bonding strength and product surface flatness. Furthermore, the integrated buffer material detection mounting position 421 on the defoaming plate 42 optimizes component layout and reduces equipment space requirements.

[0032] In at least one embodiment, the cushioning material is EV foam, the material to be bonded is a gift box, the vibrating feeder 12 is equipped with a spiral feeding track, and the dispensing station 23 is equipped with a hot glue gun mounted on a robotic arm. The robotic arm will drive the hot glue gun to precisely dispense glue onto the material to be bonded according to a preset motion trajectory. By dispensing glue onto the material to be bonded with the hot glue gun, it is ensured that the glue can be evenly applied to the material to be bonded in a suitable form, and it can adapt to long-term continuous dispensing work. The camera assembly 221 is a high-resolution industrial camera. The camera assembly 221 is mounted on the side worktable by a bracket, which can realize clear imaging of the entire surface of the material to be bonded, without occupying the flow channel 2. The conveying space of 1 also facilitates the maintenance and debugging of the camera assembly 221 by the operator. The positioning station 13 and the bonding station 24 are connected by a robot arm to install the buffer material jig 5. The buffer material jig 5 picks up the buffer material and bonds it to the material to be bonded. The buffer material detection device 44 is a detection probe to detect whether there is buffer material on the material to be bonded. The robot arm adopts a multi-axis linkage servo robot arm with high-precision motion control capability. The defoaming drive 41 is a cylinder to ensure that the defoaming plate 42 is pressed down smoothly and slowly, avoiding damage to the buffer material and the material to be bonded due to impact, and further improving the bonding firmness of the buffer material and the material to be bonded.

[0033] like Figures 1-8 As shown, the automatic bonding and assembly device has a compact structure and stable operation. It uses a frequency controller 11 and a vibrating material tray 12 for material supply, which improves the efficiency of operation. It can realize direct operation on the production line, reduce the handling of cushioning materials and materials to be bonded, realize automatic glue dispensing, and the machine can complete the production capacity. It also reduces the number of operators by at least two, and improves the efficiency and accuracy of bonding between cushioning materials and materials to be bonded. The incoming materials of cushioning materials, such as foam, can be changed from whole sheets with adhesive backing to small units without adhesive backing, thereby reducing the cost of incoming materials. The bonding and assembly component 2 is set up with different stations for material distribution according to different functions such as feeding direction detection, glue dispensing, bonding, debubbling and detection. The reasonable planning of the station layout improves the efficiency of the automatic bonding process of cushioning materials and reduces labor costs.
